8. Water at 15°C flows out of the elbow at 0.0153 m3/s. The water is discharged to the atmosphere at section 2. The pipe diameter is D1 = 100 mm and D2 = 30 mm. The pressure pi = 2.3 atm (gage). Neglect the weight of the elbow and the water within it. Neglect elevation change between 1 and 2. Determine the force on the flange bolts at section 1. (40 points)
Water sprays out of a sprinkler as shown in the picture.
At point 1, the diameter is D1=4in, Q=245 gpm, P1=34 psig.
At point 2 , the diameter of the nozzle is D2=1 in, Flow rate is
still Q=245 gpm.
Ignoring the weight of water, calculate:
a) V1 N=AND V2
b) force on the flange @section 1
c) total head loss of elbow and nozzle, hL

Water flow in a pipe and then exit through a bended nozzle as shown in Figure 3. The nozzle is connected to the main pipe using a flanged joint at (1). The diameter of the pipe is D1 10 cm and is constant, whilst the diameter at the outlet section of the nozzle (2) is D2 3 em. The flowrate of the water is Q = 15 liter/s and the water pressure at the flange is Pi 230 kPa. By...
Water is flows through a nozzle at a rate of 18 ft/s (Q) and discharge into the atmosphere. The diameters Di 15 in. and D2- 5.5 in. The pressure measured at section 1 is P1-3100 1b/ft (gage). Determine the horizontal force required at the flange to hold the nozzle in place. Indicated the direction of the force (to the left or to the right). D2
Water is discharged through an elbow nozzle as shown below. PB - Patm ds The exit velocity VB = 30 ft/s, the inlet diameter da = 0.5 ft, the exit diameter dB = 0.25 ft. For water density, use p = 32.2 lb/ft = 1.94 lb/ft. Assume steady flow. Neglect the weight of the nozzle and the water in the nozzle.

Water (p = 1,000 kg/m?) flows steadily through a 90° elbow and exits as a free jet through a nozzle, as shown below. The measured upstream gage pressure is 800 kPa. Neglect body forces and viscous effects, and disregard the height of the elbow/nozzle combination. The water velocity at any cross section is assumed to be uniform. However, the water velocity inside the elbow is not negligible compared to that in the nozzle. Consider the following: Determine the velocities V,...
A
water spray system discharge water to the atmosphere. Water is
released to the atmosphere by two identical nozzles at the same
velocity. The pipe diameter is 6 inch and the nozzle diameter are 3
inches. If the vertical reaction force on the flange is 14 kN in
magnitude pointing down, determine the velocity V1 within the pipe
in m/s. Neglect gravitational force and inlet pressure is P1=250kPa
gage.

Problem 7.2 For the flow through the pipe with an 180 degree elbow and the nozzle shown in the figure below: (a) Determine the loss in available energy from section 1 to section 2 (b) How much additional available energy is lost from section (2) to where the water comes to rest? 0.3m Pig -1 bar v1 1.5 m/s D2-0.15m Patm V2
5) Oil (S.G=0.9) flows enters the pipe shown through the bottom inlet at a rate of 0.25 m/min and is discharged to at P. - 76 kPa the nozzle outlet at the top. The pipe has a diameter Di = 40 mm at the entrance and a diameter D2 = 20 mm at the exit. If P. = 76 kPa, P2 =20 kPa, and the weight the oil and the piping is negligible, what is the reaction moment at flange...
